 WHAT TO EXPECT
As part of the Loop 1604 North Expansion project, TxDOT has planned major closures along Loop 1604 in north Bexar County to allow crews to set steel beams at the interchange and to prepare for the opening of new mainlanes.
- Loop 1604 eastbound and westbound mainlanes will be closed from La Cantera Parkway to Stone Oak Parkway.
- I-10 eastbound and westbound mainlanes will also be closed through the Loop 1604 interchange.
- Loop 1604 eastbound and westbound frontage roads will be closed through the interchange.
- All four cloverleaf ramps will be closed at the interchange.
The closures are scheduled to begin at 9 p.m. on Friday, May 17 and are expected to be completed by 5 a.m. on Monday, May 20, weather permitting. Local law enforcement will direct traffic through the intersections during this time.
A portion of the Loop 1604 closure, from Vance Jackson Rd. to Stone Oak Parkway, is expected to open by the end of day Saturday, May 18. Once open, this section will have an additional mainlane open to traffic for a total of 3 mainlanes in each direction.
Additional major closures will continue at the Loop 1604 and I-10 interchange to allow crews to install steel beams for the construction of the flyover ramps. Detailed closure information will be shared each week as the work is confirmed. Major construction closures will not be scheduled during the Memorial Day holiday weekend.
Please note, construction schedules are subject to change and weather permitting.
